What is the role of "range-bound" MMIDs???

  1. When I'm looking at the Level II or TotalView for any given NASDAQ stock, I see MMs that just sit pretty far away from the nearest ask/bid prices and never do anything.

    They constantly adjust their bid/ask prices, but of course, they never get close to the actual price.

    What's the role of these guys?
